The combination of hopping movement and the original movement can be greatly enhanced scope of robot s activities.

The design of the mechanism and the realization of the hopping movement and running movement are introduced in detail.

A kinematics equation of a bouncing ball on a vibrating table is studied , the dynamic behavior of the ball was simulated from regular to irregular motion by computer; moreover, influence of two parameters ( the comeback coefficient α of collide dissipation and the ratio β of acceleration of vibrating table to acceleration of gravity ) on behavior of the ball is discussed.

An experimental electronic circuit is designed for simulation of a bouncing elastic ball on a vibrating table.

Intraocular pressure monitoring in diving experiment of model eye with tension sensor.;

We have developed a video analysis system is named as DivingVAS specified for diving training.

Further researches of the diving training aim at the evaluation of technical training,individual divers strength training,female divers nutrition and weight control and psychological training before.

Through analysing the run-up speed and the results of some excellent sportsmen,a theory is advanced that the running speed is a decisive factor for long jump.

Taking the Retrieval System of China Periodical Full Text Database as a tool,retrieving throughly the theses published from 1995 to 2005 about long jump, this paper analyzes the theses about long jump published in core and non-core publications on physical education listed in China Academic Per-iodical Database.

This paper compares the factors acting at the beginning of man s long jump from the literature about the outstanding athletes worldwide,and points out that the momentary vertical velocity is another important factor affecting the jump.
